5. Adjust clearance between rear face of side gear and thrust
washer by selecting side gear thrust washer. Refer to RFD-31,
"AVAILABLE PINION HEIGHT ADJUSTING WASHERS" .
Use two feeler gauges to prevent leaning of side gear as show-
ing figure.
SIDE BEARING PRELOAD
A selection of carrier side bearing adjusting washers is required for successful completion of this procedure.
1. Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.
2. Place the differential case, with side bearings and bearing races
installed, into gear carrier.
3. Insert left and right original side bearing adjusting washers in
place between side bearings and carrier.
4. Install the side bearing caps in their correct locations and torque
the bearing cap retaining bolts.
5. Turn the carrier several times to seat the bearings.Clearance between side gear thrust washer and dif-
ferential case

6. Measure the turning torque of the carrier at the drive gear retain-
ing bolts with a spring gauge, J-8129.
7. If the turning torque is not within the specifications, correct the
torque as follows:

If the turning torque is less than the specified range, install
washers of greater thickness.

If the turning torque is greater than the specification, install
thinner washers.

See the SDS section for washer dimensions and part num-
bers.
8. Record the total amount of washer thickness required for the
correct carrier side bearing preload.
9. Remove the carrier from the final drive housing. Save the
selected washers for later use during the assembly of the final
drive unit.
PINION GEAR HEIGHT
1. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the differential shim
selector tool, J34309.

Pinion front bearing; make sure the J34309-3 pinion front bear-
ing seat is secured tightly against the J34309-2 gauge anvil.
Then turn the pinion front bearing pilot, J34309-5, to secure the
bearing in its proper position.

Pinion rear bearing; the pinion rear bearing pilot, J34309-8, is
used to center the pinion rear bearing only. The pinion rear bear-
ing locking seat, J34309-4, is used to lock the bearing to the
assembly.Specification

Installation of J34309-9 and J34309-16; place a suitable 2.5 mm (0.098 in) thick plain washer between
J34309-9 and J34309-16. Both surfaces of J34309-9 and J34309-16 must be parallel with a clearance of
2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into the final drive hous-
ing. Then place the pinion preload shim selector tool, J34309-1,
gauge screw assembly.
4. Assemble the pinion front bearing inner race and the J34309-2
gauge anvil. Assemble them together with the J34309-1 gauge
screw in the final drive housing. Make sure that the pinion height
gauge plate, J34309-16, will turn a full 360 degrees. Tighten the
two sections together by hand.
5. Turn the assembly several times to seat the bearings.
6. Measure the turning torque at the end of the J34309-2 gauge
anvil using torque wrench J-25765A.

7. Place the J34309-11 “R200A” pinion height adapter onto the
gauge plate and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.
Pinion Height Adjusting Washer Selection
1. Now, position the side bearing discs, J25269-4, and arbor firmly
into the side bearing bores. Install the bearing caps and tighten
the cap bolts to proper torque.
2. Select the correct standard pinion height adjusting washer thick-
ness. Select by using a standard gauge of 3 mm (0.12 in) and
your J34309-101 feeler gauge. Measure the distance between
the J34309-11 pinion height adapter including the standard
gauge and the arbor.
3. Write down your exact measurement (the value of feeler gauge).

4. Correct the pinion height washer size by referring to the “pinion
head number”.
There are two numbers painted on the drive pinion. The first one refers to the drive pinion and drive gear as a
matched set. This number should be the same as the number on the drive gear. The second number is the
“pinion head height number”. It refers to the ideal pinion height from standard for quietest operation. Use the
following chart to determine the correct pinion height washer.
5. Select the correct pinion height adjusting washer as follows. Refer to RFD-31, "
AVAILABLE PINION
HEIGHT ADJUSTING WASHERS" .
6. Remove the J34309 differential shim selector tool from the final
drive housing. Then disassemble to retrieve the pinion bearings.
TOOTH CONTACT
Checking gear tooth contact pattern is necessary to verify correct relationship between drive gear and drive
pinion.
Hypoid gears which are not positioned in proper arrangement may be noisy and/or have a short life. Check
gear tooth contact pattern to obtain the best contact for low noise and long life.
